Hello, I'm a new member to your forum, I have a question. Is possible to make a short Lsp with to draw a line that represents the intersection of two 3DFACE (not coplanar). Basically I would digitize three vertices of first 3DFACE and then the three vertices of a second 3DFACE, lsp procedure should draw the line of intersection. Many thanks Attached a simply dwg uploads/669992/3dface_intersection.dwg" rel="nofollow - uploads/669992/3dface_intersection.dwg screenshot: white = 2 3dface not complanar blue = intersection line green = maximal projection of 3dfaces on intersection line  |

hi, thaks, but im using IntelliCAD engine (ProgeCAD release), this commands are not contemplated. I think the best solution for me is through a lsp program. With apl.lsp (found on http://www.cadtutor.net/forum/archive/index.php/t-50376.html" rel="nofollow - http://www.cadtutor.net/forum/archive/index.php/t-50376.html ) is possible to find half solution for a correct and intermediate UCS, but cannot draw directly intersection line. |
